The Foundation of Knowledge Model / Reading and Sharing Nursing Informatics

Humans acquire data and information in bits and pieces and then transform the information into knowledge. The information-processing functions of the brain are frequently compared to those of a computer, and vice versa. Humans can be thought of as organic information systems that are constantly acquiring, processing, and generating information of knowledge or knowledge in their professional and personal lives. they have an amazing ability to manage knowledge. This ability is learned and honed from birth as individuals make their way through life interacting with the environment and being inundated with data and information. Each person experiences the environment and learns by acquiring, processing, generating, and disseminating knowledge.

Radiofrequency Identification (RFID) vs. Barcode /Nursing Informatics Reading and Sharing

A primary difference between radiofrequency identification (RFID) and barcode is that RFID has great read range. While the read range for barcode ranges from inches to a few feet, passive ultra-high frequency (UHF) RFID ranges up to 40 feet if readers are fixed or up to 20 feet if readers are handheld. Active RFID has a read range hundreds of feet. Active RFID tags are battery powered and emit a signal while passive RFID tags require activation by a reader.

Relational Database Management System (RDBMS) / Nursing Informatics Reading and Sharing

The abbreviation RDBMS refers to relational database management system. RDBMS is a system that uses a relational model to manage data. The relational model was developed by Codd and utilizes a table structure with each item within the table having a distinct identifier. The tables comprise unique rows (records) and columns (fields). The tables (which comprise the relationship) can be manipulated and mined to create new tables from the data that are present.

Usability Tests (Reading & Sharing Cont.)

  • Heuristic Evaluation or Heuristic Inspection Methods
    • the most popular of what are called “discount usability evaluation”
      • because they are typically easy to do, involve fewer than 10 experts, and are much less expensive than other methods.
    • the objective is to detect problems early in the design process, when they can be most easily and economically corrected.
    • they are called “heuristic” because evaluators assess the degree to which the design complies with recognized usability rules of thumb or principles, such as those proposed by Nielsen (1994) (retrieved from https://www.nngroup.com/articles/ten-usability-heuristics/)
      1. visibility of system status
      2. match between system and the real world
      3. user control and freedom
      4. consistency and standards
      5. error prevention
      6. recognition rather than recall
      7. flexibility and efficiency of use
      8. asthetic and minimalist design
      9. help users recognize, diagnose, and recover from errors
      10. help and documentation
